Hi,

I'm new to Windows PE and I'm trying to use the serial COM port to communicate to a device.

My problem is that my PE build/image cannot use the serial COM port. It won't detect the COM ports.

Any idea on how to add support or detect COM ports in PE?

Thanks.

Make sure you start the serial port service:

net start serenum

Then install the driver:

devcon install x:\windows\inf\msports.inf ACPI\PNP0501

*devcon will need to be downloaded from MS.

After I do both of these, I am able to use my apps to communicate to COMx

Hi,

make sure that SERENUM.SYS is in your Winpe Directory under i386\windows\System32\drivers , make also sure msports.inf is under i386\Windows\inf .

Then it should work with:

devcon install x:\windows\inf\msports.inf *PNP0501

if it's not started use:

net start serenum

check if it gots installed by typing regedit.exe and jump to:

HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\SERIALCOMM

look if there is sth. on the right side like \Device\Nmserial0 COM1 or sth. similiar.

If so it gots installed.

regards
